Such, for instance, was the attitude of the Assyrians toward the civilization of the Chaldeans; of the Iberians, Celts, and Illyrians towards that of the Romans. If, then, the Cherokees, the Catawbas, Muskogees, Seminoles, Natchez and other tribes, still preserve a feeble impress of the Alleghanian civilization, I should not thence conclude that they are the pure and direct descendants of the initiatory element of that people, which would imply that a race may once have been civilized, and be no longer so. I should say, on the contrary, that the Cherokees, if at all ethnically connected with the ancient dominant type, are so by only a collateral tie of consanguinity, else they could never have relapsed into a state of barbarism. The other tribes which exhibit little or no vestiges of the former civilization are probably the descendants of a different conquered population which formed no constituent element of the society, but served rather as the substratum upon which the edifice was erected. It is no matter of surprise, if this be the case, that they should preserve--without understanding them and with a sort of superstitious veneration--customs, laws, and rites invented by others far more intelligent than themselves. The same may be said of the mechanical arts. The aborigines of the Carolines are about the most interesting of the South Sea islanders. Their looms, sculptured canoes, their taste for navigation and commerce show them vastly superior to the Pelagian negroes, their neighbors. It is easy to account for this superiority by the well-authenticated admixture of Malay blood. But as this element is greatly attenuated, the inventions which it introduced have not borne indigenous fruits, but, on the contrary, are gradually, but surely, disappearing. The preceding observations will, I think, suffice to show that the traces of civilization among a barbarous tribe are not a necessary proof that this tribe itself has ever been really civilized. It may either have lived under the domination of a superior but consanguineous race, or living in its vicinity, have, in an humble and feeble degree, profited by its lessons. This result, however, is possible only when there exists between the superior and the inferior race a certain ethnical affinity; that is to say, when the former is either a noble branch of the same stock, or ennobled by intermixture with another. When the disparity between races is too great and too decided, and there is no intermediate link to connect them, the contact is always fatal to the inferior race, as is abundantly proved by the disappearance of the aborigines of North America and Polynesia. I shall now speak of the relations arising from the contact of different civilizations.
